SPECIFICATION forming part Of Letters Patent N 0. 724,781, dated April 7, 1903. Application filed February 19, 1902. Serial No; 94,765. (No model.)

To ail whom it may concern.- 7

Be it known that I, WILLIAM S. BEALE, a resident of Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Stoves or Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others. skilled in the art to which it appertains to tremely simple in construction, compara tively cheap to manufacture and use, and whose operation will be perfect and result in a great saving of fuel, as well as improve the healthfulness of the heat furnished.

With this object-in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in section illustrating my improvement s. Figs. 2, 3, and 4 are'views illustrat ing the various details of construction, and Figs. 5 and 6 are views of modifications.

1 represents an ordinary hot-air furnace, the air-heating chamber being located between the furnace proper or combustionchamber 1 and the inclosing casing 2, and a suitable grate is provided in the lower portion of the combustion-chamber.

- It is to be understood that the particular form of furnace shown in the drawings is not essential, as any known form of furnace might be provided with my improvements.

3 represents a water-supply pipe which is adapted to supply water (preferably hot water) to a pipe l, which latterenters the airheating chamber, near the top thereof, and

coils about the combustion-chamber to near the bottom thereof, when it projects outward and is provided with adrip-pipe 6, as shown. With the pipe l, near the entrance to drippipe 6, a vertical pipe 7 communicates and While I have described the pipes 4., 7, and

connects with a superheating-coil 8 around the combustion-chamber, and the latter (the pipe 8)'pr0.jects at its lower end into the combustion-chamber and connects with a circular perforated discharge-pipe 9 for directing the superheated steam into the fuel to be burned therewith.

8 as separate pipes, they may constitute but one continuous pipe, if desired.

In pipe 4 at suitable points valves 10 may 'be provided for discharging live steam into the hot-air space to moisten the air and prevent the injury to buildings and furniture caused by excessively-dry heat. At the juncture of the coil 4 and water-supply pipe 3 a suitable valve and gage 12 of any approved construction may be provided.

The drip-pipe 6, above referred to, is con nected with'the lower end of coil 4- by means of a sediment-trap 13 to collect the sediment, and said trap is provided with a valve 14 to permit the cleaning thereof. This pipe 6 is adapted to carry off all water whichis not generated into steam during its passage through coil 4, and in order to prevent the pressure of steam blowing through pipe 6 I provide a series of reducers 20 in said drippipe. These reducers each comprise a cone 8o 21, open at its apex and having a cup 22 below the same supported on suitable lugs or shoulders 23 to permit the overflow of water around the outer edge of the cup, but resist the steam-pressure and prevent blowing through the drip-pipe.

Instead'of connecting the coil 4 with a supply-pipe I might provide a reservoir 15 and soshape the same as to be located in close proximity to or inside the furnace to effectuo ally heat the water, as shown in Fig. 6, and

suitable safety-valves and the like may be provided to avoid all danger.

Various other forms of water-supply may be employed, as the particular'source of suppl yis immaterial. I might also provide other means for directing the superheated steam into the fuel. For instance, as shown in Fig.

5, I might provide a circular discharge-pipe 24 outside the fire-pot 25 and provide the pipe 24. with outlet-spouts 26, projecting through the fire-pot, and locate on the latter over the spouts 26 shields or protectors 27 to prevent interference with the discharge of superheated steam due to the collection of ashes or cliukers over the spouts.

Various other changes might be resorted to in the general form and arrangement of the several parts described without departing from my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fullydescrihed my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a combustionchamber, of a coiled pipe encircling the same approximately from end to end thereof, means for supplying water to one end of said coil, a superheating-coil also encircling the combus- 1ion-chamberapproximately from end to end thereof and communicating, at one end with the other end of the water-coil, and means for discharging superheated steam from the superheatingcoil into the combustion-chamher.

2. The combination with a combustionchamber, of a coiled pipe encircling the same, means for supplying water to the cooler end of said pipe, a superheating-pipe also encircling the combustion-chamber, a pipe connecting the hotter end of the water-pipe with the coolerend of superheating-coil,and means communicating with the hotter end of the superheating-coil for discharging superheated steam into the combustion-chamber.

The combination with a fire-box and a vertical combustion-chamber over the same, of a water-coil encircling the combustionchamber, a water-pipe communicating with the upper end of said water-coil, a superheating-coil encircling the combustion-chamber, a pipe connecting the lower end of the watercoil with the upper end of the superheatingcoil and means com municating with the lower end of the superheating-coil for discharging superheated steam into the lower end of the combustion-chamber.

4. The combination with a combustionchamber, of a coil of pipe encircling the same, means for supplying water to said coil, a superheating-coil also encircling the combustion-chamber and communicating with the outlet end of the first-mentioned coil, and a water-discharge pipe communicating with said coils in proximity to their juncture.

5. The combination with a combustionchamber, of a coil of pipe in which to generate steam, another coil of pipe communicating with the first-mentioned coil and in which to superheat the steam, and a water-discharge pipe communicating with said coils in proximity to their juncture.

6. The combination with a combustionchamber, ofa pipe in which to generate steam, another pipe communicating with the firstmentioned pipe and in which the steam is superheated, both of said pipes encircling the combustion-chamber, a water-drip pipe commnnicating with said pipes in proximity to their juncture, means in said drip for preventing the escape of steam therethrough and means for projecting steam from the superheating-pipe into said combustion-chamber.

7. The combination with a combustionchamber, of a pipe encircling the same in which to generate steam, another pipe encircling the combustion-chamber and communieating with the first-mentioned pipe and in which the steam is superheated, a drip-pipe communicating with said pipes in proximity to their juncture for permitting the escape of water and a circular perforated pipe communicating with the out-let of the superheatingpipe for discharging the superheated steam into the combustion-chamber.

8. The combination with a combustionchamber, and a shell inclosing the same and forming a hot-air chamber, of a coil of pipe encircling said chamber in which to generate steam, another coil of pipe communicating with the first-mentioned pipe and in which the steam is superheated, a drip-pipe com municating with said pipes in proximity to their juncture to permit the escape of water, a sediment chamber or trap in said drip-pipe, and valves in the first-mentioned pipe for discharging steam into the hot-air chamber.

9. In a furnace, the combination with a combustion-chamber and a shell inclosing the same and forming a hot-air chamber, of a coil of pipe within said hot-air chamber and encircling the combustion-chamber, and means connected with said pipe for discharging fluid into said hot-air chamber.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

WILLIAM S. BEALE.
